Application filed September 13l 1900. Serial No. 29,926. (No model.)

T0 all whom it may concern:

Be it known that I, PERLEY L. KIMBALL, a citizen of the United States of America,resid ing and having post-office address at Bellows Falls, in the county of Windham and State of Vermont, have invented a certain` new and useful Improvement in Centrifugal Separators, of which the following is a description, reference being had to the accompanying drawings. I

The object of the improvement is the production of an apparatus for separating by centrifugal force mixed fluids of different densities, notably for separating cream from milk containing it. The apparatus is herein described as applied to such separation of cream from milk.

In the accompanying drawings, Figure l is a view in central vertical section of a centrifugal separator embodying said improvement. Fig. 2 is a view ofthe same separator in horizontal cross-section on the plane .'13 oo looking downward. Fig. 3 is a view of the same separator in horizontal cross-section on the plane a; or looking upward. Fig. i is an elevation view of a portion of each of the corrugated partitions. Fig. 5 is a side view of a portion of the upper part of both partitions. Its purpose is to show the stoppin and its relation to the two partitions.

In the accompanying drawings the letter d denotes the separatorbody or outer drum, which, as is well known, is given some thousands of revolutions per minute when in operation.

The letter b denotes the separator-cover,

l which may be secured to the separator-body by screw-thread connections with a suitable packing-ring between the body and the cover. This cover is provided with central inlet c for the inflow of full milk and an adjustable non-central outlet 'CZ for the outflow of cream.

The blue milk from which the cream hasl supported underneath by the floor of the separator-body both vertically and laterally through the medium of the pintle-journal h and supported laterally at the top by the cover.

The letter fi denotes milk-How passages through the inner partition, and 7c denotes milk-flow passages through the outer partition. Those of the inner partition are located at the outer apeXes of the corrugations; but those of the outer partition are located a little oit the outer apexes of the corrugationthat is, these two sets of milk-flow passages are non-alined as to each other, so as in a measure to obstruct the direct movement of the milk toward the inner wall of the separator-body and by that obstruction aiord increased time and opportunity for separation of cream.

The letter Z denotes cream-flow passages through the inner partition, and m denotes cream-flow passages through the outer partition. kBoth sets of these are located at the inner apexesof the corrugations. I

The letter o denotes a chamber in the cover. Its sides and top are formed by the cover, and its floor is formed by the plate o', which is secured to the cover. The full-milk inlet c lets into this chamber.

The letter n denotes tubes for distributing the incoming full milk. They deliver it directly within the corrugations of the inner partition.

The letter f denotes reinforce-rings carried by the inner partition, and g' denotes reinforce-rings carried by the outer partition. The inner partition carries blades f2.

The letter p denotes chairs fast to the Iioor g2 of the outer partition. They support the foot of the inner partition both vertically and laterally. They bear on the interior of the inner partition. The inner partition is substantially closed at the top and open at the bottom. The outer partition is substantially closed at the bottom and open at the top.

i The letter r denotes a stop-pin which is fast to the inner partition. It fits into astoppin socket r' in the separator-cover. A portion of the stop-pin intermeshes with the mortise g3 in the outer partition. This stop-pin causes the two partitions to rotate with the separator-body.

revolutions per minute.

In the operation of the machine the separator as a whole is given some thousands of The full milk is fed into the separator through chamber o. It goes thence through the tubes n to and within the corrugations of the inner partition, the delivery ends ot' those tubes being outside of the circle which is described by the creamoutlet when in rotation. The milk takes on the whirling motion of the separator, and the cream being of less specific gravity than the watery portions of the milk forms a core at the center, then rises, and inally escapes through the cream-outlet d. Meanwhile a portion of the milk works downwardly along the inner surface of the inner partition and a portion passes laterally through the milkflow passages of the inner partition. When the downward current of milk reaches the lower end of the partition, centrifugal action forces it outward laterally against the inner `wall of the outer partition, and it travels upward on that inner Wall, some of it escaping through the milk-iiow passages in the outer partition. When the milk completes that upward travel, it passes over the upper end of the outer partition and thence downwardly along the interior wall of the separator-body, finally escaping through the blue-milk outlets c. While the milk is traveling, as described, down the inner wall of the inner partition, up the inner Wall'of the outer partition, and down the inner wall of the separatorbody more or less of cream is passing laterally inward through the cream-flow passages of both partitions to the cream-core at the center of the separator. The inal effect is that the cream is thoroughly separated from the more watery constituents of the milk, commonly called blue milk. The creamiiow passages of the inner partition are within the circle which is described by the delivery ends of the tubes n in their rotation. The orifices s in the lloor of the outer partition permit any cream which may be beneath that oor to join the cream-core already mentioned.

As already stated, the inner partition is separable from the separator-cover.
